目的 探讨螺旋CT(SCT)胆管造影 (SCTC)三维成像在诊断胆管疾病中的价值及其真实性。方法 2 6例疑胆系疾病患者行经内窥镜逆行胆管造影 (ERC)和SCT胆管造影后三维成像 ,将SCTC三维成像与ERC图像进行非双盲双照 ,13例经手术病理证实。结果 SCTC成功率 10 0 % ,三维成像与ERC图像相似 ,根据SCTC三维成像可对 92 .3 % ( 2 4/ 2 6例 )肝内外胆管病变做出与ERC或手术病理一致诊断 ,SCTC三维成像对ERC未成功、显示不完全病例提供可靠的补充诊断信息。其空间分辨率及对肝内细小胆管腔内结石显示逊于ERC。结论 SCTC三维成像是无创性检查技术 ,对肝外胆管疾病诊断和治疗方法选择具有指导作用 ,可为部分病例ERC替代方法
Objective To investigate the value and authenticity of spiral CT (SCT) three-dimensional imaging in the diagnosis of biliary tract diseases. Methods Twenty-six patients with suspected gallbladder disease underwent endoscopic retrograde cholangiography (ERC) and SCT after cholangiography. Three-dimensional imaging of SCTC and ERC images were double-blind. Thirteen patients were confirmed by surgery and pathology. Results The success rate of SCTC was 100%. Three-dimensional imaging was similar to ERC images. According to the SCTC three-dimensional imaging, 92.3% (24/26) of the extrahepatic or extrahepatic bile duct lesions were diagnosed as consistent with ERC or surgical pathology, SCTC three-dimensional imaging Failure to ERC, showing incomplete cases provides reliable supplementary diagnostic information. Its spatial resolution and intrahepatic biliary duct calculi show less than ERC. Conclusion SCTC three-dimensional imaging is a noninvasive technique that has a guiding role in the diagnosis and treatment of extrahepatic bile duct diseases. It may be an alternative method for ERC in some cases
